I don't think you understand how xG works, it assesses the chances or goals by how many other players have scored from the same positions in the past, its a pretty comprehensive tool in assessing the quality of chances. How does your eye test draw on that mountain of comprehensive data to do the same, are you really saying that you can remember all the chances that have ever happened in the Premier League and can assess accordingly?
I am biased like anyone else and my outlook on Pogba has dimmed. If I say, 'Pogba's trash and other players make him look better than he is' then feel free to dismiss me.
That said, I am discrediting their opinions using Opta's xA stat, not my own opinion so in this particular case my bias is moot.
